The Decoupled Control Research of UPQC
Energy Procedia, 2011 AbstractThe double-loop strong coupling problem was existed in the model of some power devices under dq coordinate system. So the entirely decoupling control of UPQC is impracticability. A novel decoupling method is proposed in the paper [2] and the entirely decoupling model of UPQC is achieved.
